no just some extra hp. not no 500hp anymore. well thinking about hp how much hp does a bbc 454 output. its got a mild rv cam in it and stock heads. which i do want to replace sooner or later. its got the low comprssoin square ports.

 

Oh and no smog controll. And a dual plane carb most likely

 

DId you get any numbers off the 454 block. The is a huge varition in HP depending on year and application. Somewhere between 200-400 HP

 

WTF is a dual plane carb? Do you mean Dual plane manifold?

Ok to answer the question you asked a couple of posts ago about which manifold is best, the answer depends on what you want out of your engine. If you want best driveability and mid range torque go with the dual plane. If you want to maximize torque, and have a car that can move nice down the track go with the single plane. Single plane manifolds are usually tuned to an RPM range higher than a dual plane. The reason for this is a race car does not need the full RPM range of a daily driver, those engines are usually running at or near the red. Just depends on what you want out of your engine. If I am daily driving a car like yours I would go with the dual plane with a carb that is suited for your engine. A 600CFM carb can handle a mild BB just fine but if you build the engine you will need a carb that can handle more air flow such as an 800. I am going to guess by you stating a mild RV cam you can prolly run a 750 Edelbrock or Holley. Even a stock Q-jet should be fine if you are on a budget.

You know, I've never wanted to stab myself in the forehead with a spork more than after reading this whole thread.

To the original poster: Dude, you seriously need to decide what you want the car to be first and foremost. It sounds like you need something to commute with. If it is going to be your daily driver, then the BBC is definitely overkill. Those Novas came stock with about the perfect engine for a DD, the 250ci straight six. You could not kill that engine if you tried. That BBC will guzzle gas like there is no tomorrow and will kill you are the pump.

If you are going to try to build up a show car, it would be a cool choice as I have seen a lot of that last flavor of Nova done up real nice. But you are getting the cart before the horse again in trying to get it running.

If you are trying to build a sleeper, I commend your choice. I had a '77 that I put a 396 and 4 speed in. That thing ate 5.0 Mustangs all day, everyday. It had plaid seat covers, faded paint, and a cracked windshield. It was god aweful to look at, but it had the ace of spades under the hood.

You can check the specs on just about all of your current parts with some simple Google searches. You can run the VIN of your car and you will know what it came with from the factory (most likely a straight 6, TH350 and weak 10 bolt rear). You can run the part numbers on your carbs and find out what they flow from the factory (not saying that they haven't been modified). You can run the casting number of your block and find out what it was installed in originally (maybe not the exact make and model, but a range of uses and years).

All of that information can really help you figure out just exactly what you have as your starting point. Getting all of that info is a ton easier now days than it was 25 years ago when I built my first car. Back then, I spent many a day at the library looking for technical information on cars and parts. It took a while before I had all the info that you can get in about 20 minutes on the internet.

So, before you change your plans, again, or buy anything more for it. Answer one simple question and everyone here can help you get there without breaking the bank.

What do you want to do with the car?

 

dang, can i get someone to put that into a sig for me????

Just remove the "" around the [ and you will be good.

I thought i posted the answer i couple posts ago but i guess not. this is going to be a show car/fun to drive car. no its not going to be a daily driver. i probably would of stuck with the 350 if i planned it to be a DD.

 

Hi guys, just my topic I have a 68 355 stoked 4 bolt main 450 - 500 hp sbc, powerglide in my 98 z28. Have pics if someone can help me upload them????
no need for the fan there is no room, thermo fan shroud is already clearenced (cut awy) to fit water pump pully alone.
